Update the instructions for Opencv-4.10

[pavloshargan]

Hey, I understand It's been quite a long time since you posted this, but If there is any chance you would be interested in refreshing these instructions for the newest opencv/ffmpeg I would be glad to pay for your time to do that. I've posted a job on Upwork: https://github.com/xuchong/android-opencv-ffmpeg/issues/new

Hello @pavloshargan
I apologize if this comment comes across as self-promotion, but I’ve developed a platform called BountyHub, which is designed specifically for situations like this. Upwork is not designed for open source contributions, while our platform is and it's integrated into github pull requests.
